Filed: 1986-09-25
Abstract: PURPOSE:To prevent the generation of misfire in an engine conducting output increase wherein an injection quantity is increased in an engine output region and deceleration decrease wherein the injection quantity is decreased at deceleration, by further increasing the deceleration decrease during the output increase and during just after the end of the output increase to the initial stage of deceleration. CONSTITUTION:During engine operation, a control circuit 44 computes a basic injection time according to outputs from a rotative angle sensor 42 and a pressure sensor 20. Then, a cold correction factor is computed according to outputs from a cooling water temperature sensor 48 and an intake air temperature sensor 24. At the same time, an output increase factor and a deceleration decrease factor are calculated. It is determined whether or not power condition satisfied, and if YES, the output increase factor is set to a predetermined value, while of NO, the factor is set to 0. Further, the deceleration decrease factor is set to a value in such that the deceleration decrease is further increased during the output increase and during just after the end of the output increase to the initial stage of deceleration. Then, a final fuel injection time is computed according to each factor to control a fuel injection valve 16.

IPC: H04N19/00
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce codes which are discarded because of the limit of a code quantity at the time of an encoding process. SOLUTION: A code quantity control part 10 determines the timing of encoding close of an encoding circuit 3 based on the total quantity of codes of compressed image data counted by a code quantity counter 7. Excessive codes are added to a borrowed code quantity when the amount of codes of one block is less than a reference quantity and subtracted from the borrowed code quantity when more.

Abstract: PURPOSE:To give a large current to a load at a high speed by applying a bias depending on an input potential to a control electrode of an output transistor(TR) of an inverting booster and applying an input signal through a coupling capacitor to the control electrode. CONSTITUTION:An output of a differential amplifier 999 is fed to a booster 700 and each emitter of a PNP TR 104 and an NPN TR 111 connects respectively to power supply lines H1 and L1. Then collectors of both the TRs 104,111 are connected in common to be an output terminal. The resistance of resistors 102,109 is selected to be sufficiently lager to suppress the static current consumption of the booster 700. Since the dynamic signal is fed to bases of the TRs 104,111 via capacitors 103,110 on the other hand, the TRs 104,111 are sufficiently active even with a small output amplitude of the amplifier 999. Thus, the high speed performance of the amplifier 999 is not lost. Furthermore, a large current with large amplitude is supplied to a load momentarily by the current amplifier action of the TRs 104,111.
